Rhythm. Normal cardiac rhythm arises from the SA node (sinus rhythm) but pacemaker impulses can come from ectopic foci in the atria, the AV junction, and the ventricles under abnormal conditions. When an ectopic impulse occurs singly, it generates a beat; when the beat repeats itself, it becomes a rhythm.

A pressure measured in millimetres of mercury can be converted to a kilopascals reading using the following conversion factor calculation: 1  1 kPa = 1000 Pascals (Pa). 2  1 mmHg = 133.322 Pascals (Pa). 3  kPa value x 1000 Pa = mmHg value x 133.322 Pa. 4  kPa value = mmHg value x 0.133322.
